Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball holder that partially discharges a ball as a coating member from a tip end hole and rotatably holds the ball. A so-called ballpoint pen-type applicator, which is an applicator having an applicator that ejects from the tip hole through a gap between the ball and the ball holder, fills a so-called ballpoint pen-type applicator and draws clean lines without smearing when applied smoothly. The present invention relates to a liquid cosmetic filled in a liner, eyebrow, nail color, contour forming lip color, and the like.

[0002]

2. Description of the Related Art Conventionally, cosmetics mainly containing pigment, water and emulsion are filled in a container such as a bottle, and the type used by attaching to a brush is used for most eyeliners and nail colors. I have. In addition, a pencil type molded into a rod shape with a pigment and wax as main components and shaped into a pencil core is used as an eyeliner and an eyebrow. Those are commonly used as lip colors.
Further, a low-viscosity liquid cosmetic comprising a pigment, water and a solvent filled in a felt pen type or ballpoint pen type applicator is known as an eyeliner or nail color.

[0003]

However, there are various problems in the eyeliner, eyebrow, nail color and lip color. For example, with a brush type, it is difficult to draw a certain thin line, and when the lid is opened, the solvent evaporates and the ink is easily cured, which is inconvenient to carry. The pencil type and the stick type do not have a clear line, and powder or semi-solid material is applied to the skin, so that makeup is easily disintegrated. Furthermore, in the case of pen-shaped makeup tools, the tip of the pen may be clogged with pigment, making it impossible to draw.In the case of a ballpoint pen type, the viscosity of the cosmetic remains high at the time of application, so the ball will rotate unless it is pressed against the skin with considerable force at the time of application There have been problems such as the inability to draw a line and the occurrence of bleeding because the cosmetics easily move after application.

[0004] It is an object of the present invention to provide a liquid cosmetic composition which is filled into a ball-point pen type applicator so that certain fine lines can be easily drawn with a light force and the drawn lines do not bleed.

[0005]

That is, the present invention has a ball holder which partially discharges a ball as a coating member from a tip end hole and rotatably holds the ball, and passes through the inside of the ball holder. In a liquid cosmetic filled with an applicator having an applicator that discharges an application liquid from the tip hole through a gap between the ball and the ball holder, the application liquid has a non-Newtonian viscosity and a non-Newtonian viscosity index of 0. The gist of the present invention is a liquid cosmetic characterized by being in the range of 0.1 to 0.9.

Hereinafter, the present invention will be described in detail. The liquid cosmetic in the present invention has non-Newtonian viscosity. The viscosity η (Pa · s) of this non-Newtonian liquid is η
= ΜD ^n-1 (μ; non-Newtonian viscosity coefficient, D; shear rate (1 / s), n: non-Newtonian viscosity index). In this case, the smaller the value of the non-Newtonian viscosity index n, the smaller the increase in viscosity with respect to the shear rate, and the smaller the force required when the ball rotates. In order to impart the non-Newtonian viscosity, it is effective to add a polymer which imparts the non-Newtonian viscosity. Examples of polymers that impart non-Newtonian viscosity include xanthan gum, guar gum and its derivatives, galactomannan, alginic acid and its salts, succinoglucan, starch, carrageenan, gellan gum, curdlan, pullulan, ramzan gum, welan gum, and CMC. Alkali metal salts such as sodium salt of (carboxymethylcellulose), HPC (hydroxypropylcellulose) and HEC
Cellulose derivatives such as (hydroxyethylcellulose), hyaluronic acid, chondroitin sulfate, polyacrylic acid and its salts, crosslinked polyacrylic acid and its salts, crosslinked acrylic acid and acrylate copolymers and their salts, polyN -Vinyl acylamide and the like. The amount of these used is preferably 0.01 to 10% by weight based on the total amount of the cosmetic. If the amount is less than 0.01% by weight, there is a possibility that a decrease in viscosity at the time of application is small and light application cannot be performed. If it exceeds 10% by weight, the viscosity of the cosmetic may become too high and the ejection during drawing may not be smooth.

[0007] Water is used as the main solvent. Various coloring agents such as dyes and pigments can be used as coloring agents for cosmetics. For example, Red No. 2, Red No. 3, Red No. 102, Red No. 104, Red No. 105, Red No. 106, Yellow No. 4, Yellow No. 5, Green No. 3

Further, various types of resin spheres and hollow resin spheres can also be used. These can be used alone or in combination of two or more. The use amount is preferably 0.1 to 50% by weight in the total ink. 0.
If it is less than 1% by weight, the concentration is low, and if it exceeds 50% by weight, there is almost no improvement in the concentration of the trace of application, and the meaning of adding more than that is not recognized.

[0008] The water-soluble organic solvent is used to prevent drying of the tip of the applicator so that a clean line can always be drawn from the start of writing. For example, ethylene glycol, propylene glycol, 1,3 -Butylene glycol, glycerin, polyethylene glycol and the like can be used. The use amount of these water-soluble organic solvents is preferably 2 to 30% by weight based on the total amount of the cosmetic. If it is less than 2% by weight, the effect of preventing drying of the pen tip is not obtained, and if it exceeds 30% by weight, the applied wire becomes difficult to dry. In addition to the above essential components, a surfactant for adjusting the applicability to the skin, an antiseptic and fungicide, a pH adjuster, a resin for imparting fixation to the skin and water resistance of the applied cosmetic, coloring, When a pigment is used as a dispersant, for example, styrene-acrylic acid copolymer, styrene-maleic acid copolymer, acrylic acid-acrylic acid ester copolymer and other salts and shellac, humic acid and other resins, POE alkyl ether, POE alkyl phenyl ether, POE alkyl ether phosphoric acid and salts thereof,
Surfactants such as POE / POP alkyl ethers and POE sorbitan fatty acid esters can be used as needed.

The liquid cosmetic of the present invention can be prepared by a generally used method. To give an example of the case of a pigment, dispersing or dispersing a dispersing agent in water, adding the pigment thereto, and then dispersing with a conventionally known dispersing machine such as a three-roll mill or a conventionally known medium dispersing machine such as a bead mill. It can be made by adding other ingredients and stirring. At this time, coarse particles that cannot be dispersed may be removed by filtration or centrifugation to uniformize the particles. When a dye is used as a colorant, it can be obtained by mixing and stirring all components. Components that can be added other than the essential components may be added before or after dispersion.

As the ballpoint pen type applicator used in the present invention, various types of chips can be used, such as a chip made of a metal such as stainless steel or nickel silver, or a molded resin such as an acetal resin, PET or PBT. As the ball, various kinds of balls such as a cemented carbide ball mainly containing tungsten carbide and a ball mainly containing various ceramics such as zirconia and silicon carbide can be used. Further, in order to guide the liquid cosmetic material to the vicinity of the ball, a fiber bundle, a synthetic resin, or a metal rod may be used as the liquid lead-out member, or the liquid may be prevented from flowing backward from the ball holder, leaking, and discharging. A ball member serving as a valve may be disposed inside the ball holder or in a liquid storage member connected to the ball holder or a connecting member with the liquid storage member for controlling excessively, or a ball at the tip may be disposed by a coil spring or the like. May be pressed against the edge of the hole of the ball holder. Also,
When a coil spring or the like is arranged, it is preferable to suppress the resilience of the coil spring from causing excessive irritation on the skin to which the coil spring is applied. It is preferable to secure a liquid lead-out path in the attachment portion by a groove or other appropriate method. The ball diameter is preferably 0.4 mm to 2.0 mm.
If the thickness is less than 0.4 mm, the amount of the cosmetic to be discharged becomes small and the coating trace becomes extremely thin, so that a clear coating trace may not be obtained. On the other hand, if the thickness exceeds 2.0 mm, the width of the applied mark may be too wide, or the ejection amount may be too large to cause bleeding, so that the applied mark may not be clear.

[0011]

The reason why the liquid cosmetic of the present invention can be applied with a light force at the time of applying a line and the line after application does not bleed is presumed as follows. Since the applicator of the present invention is a ball-point pen type, the cosmetic is discharged through a gap between the ball and a chip holding the ball by rotating the ball held at the tip of the pen. If the gap is very narrow and the ball rotates rapidly, a considerable shearing force is applied to the cosmetic. Since the cosmetic of the present invention has a non-Newtonian viscosity, when a shearing force is applied, the structural viscosity of the thickener used in the cosmetic breaks down, and the viscosity of the cosmetic decreases, and the viscosity decreases. For this reason, the viscosity of the cosmetic is greatly reduced, so that the ball can be rotated with a light force, and as a result, it can be applied to the skin with a light force. In addition, as soon as the shear force disappears, the structure of the thickeners is formed and the viscosity increases and returns to the original viscosity, so that the cosmetic applied to the skin does not easily move over time, so that no bleeding occurs. it is conceivable that.

With respect to the liquid cosmetics obtained in Examples 1 to 4 and Comparative Examples 1 to 4, the results of applying test and bleeding test are shown in Table 1. The test applicator sample was prepared by connecting the application destination holding the ball to the liquid cosmetic obtained in the examples and comparative examples to a cosmetic tank, and arranging a backflow preventing means at an interface portion of the cosmetic. . Specifically, FIG. 1 and FIG.

That is, as shown in FIG. 1 which is an enlarged cross-sectional view of a partially omitted coating device, a coating destination holder 2 which is an injection-molded product of polypropylene resin is provided at the front end of a pipe 1 formed by extrusion molding of polypropylene resin. Are connected, and the application destination 3 is connected to the tip of the application destination holder 2. The cosmetic 4 contained in the pipe 1 is supplied to the periphery of the ball 5 as an application member through the through hole 2a of the application destination holder 2 and the middle hole 3a of the application destination 3. Cosmetic 4 in pipe 1
A backflow inhibitor composition 6a in which the polybutene is gelled by contact with the interface of, and dipped in the backflow inhibitor composition 6a;
A backflow prevention means 6 including a float 6b that substantially increases the flow resistance of the backflow inhibitor composition 6a by reducing the cross-sectional area where the backflow inhibitor composition 6a is disposed between the pipe 1 and the inner wall is disposed. are doing. This backflow prevention means 6
Moves gently forward following the movement of the cosmetic interface due to the consumption of the cosmetic 4. On the other hand, when a sudden inertia acts rearward at the opening end of the pipe 1 due to an impact at the time of dropping or the like, the viscosity of the backflow inhibitor composition and the height of the flow resistance due to the float 6b depend on the viscosity. It is possible to suppress the cosmetic 4 from moving backward.

Further, the application destination 3 holds a ball 5 made of carbide by projecting a part of a tip thereof by a ball holder 3b made of stainless steel. A coil spring 7 for urging the ball 5 in the tip direction is provided inside the ball holder 3b.
However, the rear end of the ball holder 3b is arranged so as to contact the step portion of the application destination holder 2 so that the ball 5 contacts the inner edge of the opening of the ball holder 3b to maintain liquid tightness. A plurality of grooves 2b as a cosmetic flow path are formed in the step portion of the application destination holder 2 where the coil spring 7 contacts, so that the presence of the coil spring 7 does not hinder the smooth flow of the cosmetic 4. The reason that the ball 5 is brought into contact with the inner edge of the opening of the ball holder 3b to maintain the liquid tightness in this manner is that the application destination 3 is used with the application destination 3 facing upward, because it is a cosmetic application tool. This is to prevent the cosmetic 4 from receding under its own weight and becoming scarce around the ball 5, causing the applied trace to be blurred or the cosmetic 4 not to be discharged. In addition, this applicator can be used while housed in an exterior body (not shown). However, when the interior of the pipe 1 is pressurized by the structure of the exterior body to make it easier for the cosmetics 4 to be discharged, It is also possible to obtain a reliable closed structure and to suppress unexpected ink leakage.

As shown in FIG. 2 which is an enlarged view of the portion I in FIG. 1, the tip of the coil spring 7 is formed as a straight portion 7a having no winding, and the tip is brought into contact with the ball 5. . A liquid cosmetic having a non-Newtonian viscosity index of 0.1 to 0.9 as in the present invention is a liquid having a very low fluidity compared to water. Although it is preferable to increase the gap, it is usually possible to obtain a gap that can be freely opened by the dimensional design of the ball 5 and the ball holder 3b. However, as in this example, the coil spring 7 or the like (a plate-like material such as a leaf spring, rubber, or synthetic resin may be used).
When the ball 5 is urged by the repellent member, the ball 5 moves backward only after the ball 5 is directly contacted with the skin and pressed to form a gap for discharging the cosmetic. If the force for urging the ball 5 is too large, there is a possibility that the skin may be pained by the pressing force before the ball 5 moves to such an extent that a sufficient gap for discharging the cosmetic is formed. Therefore, it is preferable to set the force required to completely push down the ball 5 of the repelling member (the force required to form a gap sufficient for the cosmetic to be discharged) to 10 g or less. In this case, the material, the linearity, the number of windings, and the spring multiplier of the coil spring 7 are adjusted to be about 5 to 7 g.

[0024]

The coating test was carried out on a writing test machine, and the load which could be drawn without blurring when writing at 3 cm / sec was measured. Bleeding test With a test sample, when a straight line was drawn on the back of the hand by 5 cm and left to dry, the average distance traveled by the cosmetic along the wrinkles of the skin was measured.

[0025]

[Table 1]

The lighter the load that can be drawn without blurring, measured with a writing tester, the lower the pressing force when actually applied to the skin. As described above in detail, the liquid cosmetic according to the present invention can be applied with a light force when applied to a skin by filling it into a ballpoint pen type applicator, and is an excellent product that does not cause a trace of application.
